Order: Amoxicillin oral suspension 15 mg/kg PO Q8h. The label on the bottle reads, "125 mg/5 mL," and the child weighs 65 pounds. Calculate the number of milliliters that you should administer per dose. Do not provide the unit of measurement. Only provide the number. Round to one decimal place (tenths).
The Correct Answer is ["17.7"]
First, convert the child’s weight from pounds to kilograms:
65 ÷ 2.2 = 29.5 kg
Next, calculate the dose:
15 mg × 29.5 = 442.5 mg per dose
Now, use the concentration (125 mg/5 mL → 25 mg/mL):
442.5 ÷ 25 = 17.7
Answer: 17.7
